## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability slug-underscore-24-unicode-c7579f90 -d '<json body>'
```

Example prompt: Turn 'Café au Lait Morning Brew Special Edition' into a slug using underscores, keeping any Unicode letters, and cap it at 24 characters.

## When to prefer this

Choose this endpoint when you need underscore-separated slugs that retain Unicode letters and must be capped at 24 characters — particularly useful for multilingual content or systems that accept Unicode identifiers but have strict length limits. If a free sandbox equivalent (POST /v1/sandbox/slug-underscore-24-unicode) is available, prefer that first to avoid the $0.004 USDC cost.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Input exceeding 100,000 characters is rejected
- Payment of exactly $0.004 USDC not provided results in 402 Payment Required
- Network timeout or service unavailability returns 5xx error

## How this service works

Call when an agent needs a slug using "_", capped at 24 characters, keeping Unicode letters. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/slug-underscore-24-unicode first.

## Output

Returns a slugified version of the input text where words are joined by underscores, Unicode letters are preserved, and the total length is capped at 24 characters.
